When we were in the Moab area in March, my husband and I went on the ranger led hike. I decided it would be a good way to become familiar with the area if I am able make a return visit. The hiking was broken up with an interpretive program. I was surprised to find the visual aids used actually helped me get a better understanding of the area's geology. The hike turned out to be an enjoyable experience and I recommend it if you are playing tourist at Arches.
These are some pictures I took.
